BARREL-RECOIL GUN Specification of Letters Patent.

Patented Dec. 28, 1920.

Application filed September 3, 1920. Serial No. 408,092.

To all whom it may concern:

Be it known that I, AUGUST SoHMfioKING, residing at Essen, Germany, acitizen of the German Republic, have invented a certain 6 new and usefulImprovement in Barrel- Recoil Guns, of which the following is aspecification.

The object of the present invention is to provide a barrel recoil gunwhich can be ele- 10 vated without the aid of an equalizer and with theminimum possible expenditure of power and time and which at the sametime possesses a small firing height.

The invention will be described with reference to a land gun illustratedin side elevation partly in section in the accompanying drawing.

The cradle B which carries the gun barrel C is mounted by means ofhorizontal trunnions b in the cheeks of the gun carriage A which is setup on a platform or the like. The cradle B carries the cylinder of arecoil brake and of a running out gear, the piston rods I) of which areattached to a ring 0 fixed to the gun barrel. Between the cradle B andthe cheeks A of the gun carriage is interposed an elevating gear E ofthe usual construction.

The gun is also provided with arrangements which enable the gun barrelto be drawn back out of the firing position shown in the drawing by fulllines into the recoiled position indicated by dot and dash lines andsecured in this position. These arrangements are not shown in thedrawing as they can be constructed in the manner known for socalleddiiferential recoil guns. They may consist for example of a ratchetWindlass for drawing back the gun barrel and a pawl 40 catch forautomatically securing the gun gun barrel, etc.) is exactly orapproximately compensated in respect of the axis of the trunnions, whenthe gun barrel is in the recoiled position.

When the gun is being served the procedure (as far as this specificationis concerned) is as follows :Before the first shot is fired the gunbarrel which is in the horizontal position is drawn back by means of theabove mentioned arrangement into the recoiled position I indicated bydot and dash lines and secured therein by means of the catch. Thenecessary elevation is then imparted to the gun barrel by means of theelevating gear E. The position which the breech end of the gun assumeswhen in the recoiled position and when it is elevated to the utmostpermissible limit, is indicated at II by dot and dash lines.

The elevation of the gun barrel can be effected without the aid of anequalizer and with a very little expenditure of power and time, as theweight of the parts. oscillating about the horizontal trunnions isexactly or approximately compensated with respect to the axis of thetrunnions when the gun barrel is in the recoiled position. After it hasbeen elevated the gun barrel is released by freeing the catch and thegun barrel then runs out under the action of the running out gear intothe position in which it is fired.

If the elevation of the gun barrel is to be altered after the gun hasbeen fired or the gun is to be loaded in the recoiled position, the gunbarrel is secured in this position; otherwise the catch can be held inthe inoperative position, so that the gun barrel runs out againimmediately after the termination of the recoil.

In consequence of the above described arrangement of the trunnions, thisgun, in comparison with those guns in which the horizontal trunnions areso arranged, that when the gun barrel is in the firing position, theweight of the parts of the gun to be elevated is compensated in respectof the trunnion axis, can under otherwise equal conditions (viz. equalmaximum elevation and equal length of recoil) have a smaller firingheight because in the present gun the breech end of the gun barrel, whenin the recoiled position is at a lesser distance from the axis of thetrunnions than in the known guns above mentioned.

Claims:

1. A gun of the class described comprising a gun barrel, a recoilmechanism, a gun carriage, horizontal trunnions for mounting said barrelon the carriage, the axis of oscillation formed by the trunnions beingad-v jacent the breech of the barrel and so disposed that when thebarrel is secured in recoiled position the weight thereof is balancedupon the trunnions, as and for the purpose set forth.

2. An arrangement for guns which comprises a recoiling gun barrel, arecoil mechanism, a gun carriage, means for supporting the barrel foroscillation at points adjacent its breech end, the point of support ofthe barrel being such that when the barrel is recoiled the weightthereof is balanced upon 10 the point of oscillation, substantially asdescribed.

The foregoing specification signed at Essen, Germany, this 18th day ofMay, 1920.
